Verified step by step guidance

Understand the question: The problem is asking about the type of polymers that make up gels. Gels are a type of material that can hold a significant amount of water while maintaining their structure.

Recall the properties of gels: Gels are known for their ability to absorb and retain water. This property is due to the presence of polymers that interact well with water molecules.

Analyze the options: Consider the characteristics of each type of polymer: (1) Ionic polymers are charged and may interact with water, but they are not the primary type used in gels. (2) Hydrophilic polymers are water-attracting and can form networks that trap water, making them ideal for gels. (3) Aromatic polymers are generally hydrophobic and do not interact well with water. (4) Hydrophobic polymers repel water and are not suitable for forming gels.

Focus on hydrophilic polymers: Hydrophilic polymers have functional groups (e.g., hydroxyl, carboxyl, or amine groups) that form hydrogen bonds with water, allowing them to retain water and form the gel structure.

Conclude: Based on the properties of hydrophilic polymers and their ability to interact with water, they are the primary type of polymer used in gels.
